CSS effect followed by: circle after another circle

Question

Link: http://tympanus.net/Development/IconHoverEffects/#set-7

When you flip any circle icon in the link above, it disappears in CURVE (which, I believe, is another WHITE circle after the circle that appears). I don't need this rollover effect, but I want to have a simple curve next to the circle.

I believe that we can do this with the class css after. I tried to create a class .circleand placed it afterwith a 10px field increase, but it does not work.

Can anyone check my code or suggest how to do this?

CSS

.circle {
    background:#000;
    color:#FFF !important;
    text-align:center;
    -moz-border-radius:75px;
    -webkit-border-radius:75px;
    border-radius:75px;
    width:100px;
    height:100px;
    border:5px SOLID RED;
}

.circle:after {
    background:green;
    -moz-border-radius:75px;
    -webkit-border-radius:75px;
    border-radius:75px;
    width:120px;
    height:120px;
    margin-left:20px;
    margin-top:20px;
}
